[0002] A CNC machine tool is an automated machine tool equipped with a program control system. It can perform operations such as cutting, grooving, drilling, reaming, boring, and reaming on workpieces. During the use of a CNC machine tool, a worktable is usually provided for placing the workpiece.

[0003] For example, Chinese utility model patent CN212444143U discloses a height-adjustable CNC machine tool worktable, including a worktable with support columns at the bottom and near the four corners. Each support column has a limiting groove, a movable groove at the top of the limiting groove, a limiting plate within the limiting groove, and a movable column at the top of the limiting plate. A fixed column is located at the bottom of the worktable between the two support columns. The fixed column has a rectangular groove, a gear groove on one side of the rectangular groove, a locking pin within the rectangular groove, and a gear within the gear groove. This utility model, through the fixed column, locking pin, and gear, is fixed to the two support columns by the fixed column, providing support for the locking pin. By rotating the gear, the locking pin can move up and down within the fixed column, thus moving the worktable up and down, allowing the height of the worktable to be adjusted.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a CNC machine tool worktable with a cleaning structure, including a counterweight 1, a worktable body 2, a gear plate 3, a gear 4, a limiting plate 5, a spring 6, a height sensor 7, a display 8, a controller 9, a receiving plate 10, a worm gear 11, a worm 12, a fixing block 13, a motor 14, a brush plate 15, a slider 16, an electric rail 17, a connecting plate 18, a collection box 19, and a magnetic strip 20. The worktable body 2 is positioned above the counterweight 1, and the receiving plate 10 is nested and fitted inside the worktable body 2. The brush plate 15 is engaged with the outer right side of the worktable body 2. A height adjustment structure is provided between the counterweight 1 and the worktable body 2, wherein the height adjustment structure includes a gear plate 3, a gear 4, a limiting plate 5, a spring 6, and a height sensor 7. Sensor 7, display 8, and controller 9 are provided. The toothed plate 3 is symmetrically fixedly connected to the lower middle part of the left and right ends of the workbench body 2.

A rotation adjustment structure is provided in the inner middle part of the workbench body 2. The rotation adjustment structure includes a receiving plate 10, a worm gear 11, a worm 12, a fixing block 13, and a motor 14. The worm gear 11, which engages with the workbench body 2, is fixedly connected to the lower middle part of the receiving plate 10. A cleaning and collection structure is provided on the outer side of the outer end of the workbench body 2. The cleaning and collection structure includes a brush plate 15, a slider 16, an electric rail 17, a connecting plate 18, a collection box 19, and a magnetic strip 20. The slider 16 is symmetrically fixed under the brush plate 15. Specific Implementation Example 1

[0029] To address the problem in existing technologies that make it difficult to quickly and accurately adjust the height of the worktable, this embodiment employs the following technical solution: Figure 1 , Figure 2 and Figure 3First, the workbench can be placed in the position to be used. Then, the operator can step on the limiting plate 5 that is engaged on the inner side of the counterweight seat 1. Under the pressure of the equal-spaced fixed springs 6 on the inner side of the lower end of the counterweight seat 1 and the limiting plate 5, the buckle of the limiting plate 5 and the gear 4 set on it is disconnected. Since the gear 4 is externally meshed with the toothed plate 3 that is nested and attached to the counterweight seat 1, and the workbench body 2 is fixedly connected to the toothed plate 3, the purpose of disconnecting the limiting plate 5 and the gear 4 is achieved by disconnecting the gear 4 from the toothed plate 3. Then, the height of the workbench body 2 can be adjusted by holding the workbench body 2 to raise and lower the toothed plate 3 within the counterweight seat 1 until the workbench body 2 is in a suitable position.

[0030] During the height adjustment of the workbench body 2, the controller 9, which is embedded in the inner side of the upper rear end of the workbench body 2, controls the height sensor 7 and the display 8, which are embedded in the inner side of the rear end of the workbench body 2, to work together. This allows the height sensor 7 to sense the position of the workbench body 2, and the display 8 to display the data sensed by the height sensor 7, thus achieving the purpose of precise height adjustment of the workbench. After the adjustment is completed, the foot pedal of the limiting plate 5 can be loosened, so that the limiting plate 5 can be engaged with the gear 4 under the elastic force of the spring 6, thus limiting the gear 4. This allows the gear 4 to limit the toothed plate 3, thereby facilitating the rapid and precise height adjustment of the workbench. Specific Implementation Example 2

[0032] To address the problem in existing technologies that make workpiece rotation inconvenient and hinder convenient CNC machining, this embodiment employs the following technical solution: Figure 1 , Figure 2 and Figure 4 During the use of this workbench, the motor 14, which is fixedly installed under the workbench body 2 by clamps and screws, can be controlled by the controller 9 to operate. The motor 14 drives the worm gear 12 connected to its left side to rotate under the locking and limiting position of the fixing block 13. Since the worm gear 12 is meshed with the worm wheel 11 which is locked with the workbench body 2, and the receiving plate 10 which is flush with and fits on the workbench body 2 is fixedly connected to the worm wheel 11, the operation of the motor 14 makes it easy for the worm gear 12 to drive the worm wheel 11 to rotate under the locking and limiting position of the workbench body 2. This allows the worm wheel 11 to drive the receiving plate 10 to rotate inside the workbench body 2, thereby facilitating the rotation of the workpiece placed on the receiving plate 10 for CNC machining. Specific Implementation Example 3

[0034] To address the problem of inconvenient cleaning and collection of processing waste in existing technologies, this embodiment employs the following technical solution: Figure 1 , Figure 2 and Figure 5After the workbench is used, the controller 9 can control the electric rails 17 fixedly installed on the inner sides of the front and rear ends of the workbench body 2 to perform operations, so that the electric rails 17 drive the sliders 16 installed inside to slide. Since the sliders 16 are fixedly connected to the outside of the brush plate 15 nested and attached to the workbench body 2, and the lower sides of the left and right ends of the workbench body 2 are symmetrically fixed with connecting plates 18, and the collecting boxes 19 are attached to the connecting plates 18, the collecting boxes 19 and the connecting plates 18 are magnetically fixed by magnetic strips 20. Therefore, through the operation of the electric rails 17, the sliders 16 can drive the brush plate 15 to move, so that the brush plate 15 can clean the waste generated by processing on the workbench body 2, and facilitate the collection of the waste generated by processing into the collecting box 19. After long-term use, the connection between the collecting box 19 and the connecting plate 18 via the magnetic strips 20 can be disconnected to clean the waste collected in the collecting box 19. All the electrical components mentioned above are existing technologies and will not be described in detail here.
